The movie, a contemporary re-imagining of Marvel's longest-running superhero team, stars Miles Teller as Reed Richards / Mr. Fantastic, ("he knows answers to questions we don't even know to ask yet"), Kate Mara as Susan Storm / The Invisible Woman, Michael B. Jordan and Jonny Storm / The Human Torch and Jamie Bell as Ben Grimm / The Thing.
The new trailer, which followed a teaser released in January, shows how, after they teleport to an alternate, dangerous universe, they are transformed into, yep, superheroes, with awesome super powers. (The Human Torch for the win!).
